SYSTRAN was originally developed around a data acquisition system and was primarily intended for use in analysis of periodic and transient signals. Although the system included some capability for handling random data it was limited. The additions have been made for the purpose of handling unusual data (including random). Extensions of the capability of the original program, corrections to the original program, and listings of all modifications and additions are described. In particular this report describes the addition of computing capability for accomplishing Digital Filtering, Probability Density Function Calculation, and Random Number Generation. The report discusses all aspects of the program essential to competent usage. (Author).
